PNEUMATIC TIRE.

Specification of Letters Patent.

Application filed October 30,1905. Serial No- 285,096.

Patented June 4, 1907.

To all whmn it m-a'y concern:

Be it known that I, ARTHUR JAMES JACK- SON, of the city of Toronto, inthe county of York, in the Province of Ontario, Canada, have inventedcertain new and useful Iniprovements in Pneumatic Tires, of which thefollowing is the specification.

My invention relates to improvements in pneumatic tires particularlyadapted to automobiles and the object of the invention is to devise asimple, strong, durable and readily detachable means for securing thetire on the wlnael, which will require but a minimum amount of time toremove the tire in case of a puncture and to replace it again and ableretaining edge, detachable clips arranged to secure the detachableretaining-edge of the rim in position and a retaining ring secured tothe rim and extending around the same and designed to form interiorwalls to aid in holding the retaining bead of the envelop in positionboth on the permanent and removablc side oi the rim as hereinafter moreparticularly explained.

Figure l, is a perspective view partially broken away and in sectionshowing portion of a folly, rim and tire of an automobile and the partsinvolved in my invention. Fig. 2, is a longitudinal section of Fig. 1.Fig. 3, is a cross section.

in the drawings like letters of reference in dicate corresponding partsin. each figure.

A is the folly of the wheel, which is provided with the face plates A.

B the rim which is provided with one curled edge 15 and a detachablecurled edge l?" at the opposite side.

is a retaining ring oia broad V-sbapcd cross section having one or moreteats O, which ht in across groove l) in the rim, which enables theretaining ring (.3 to be withdrawn laterally but prevents it fromcreeping cirentially.

. no envelop and i the internal air tube. it will be noticed that theenvelop E is of the usual construction and i'orrned with the holdl'astbeads i iwhich are held in position by the curled edge B at one side andthe detachable curled cdgcou the opposite side, such dctachable curlededge being retained in position. by the (lips l having the teats l!extending into the rec sses B. The clips 1 may be located at any desiredposition and lugs C throughwhich extend the right and I left handthreaded spindle H.

I is a worm wheel secured centrally of the spindle H and J is a wormmeshing therewith and rovided with a suitably sided turning end i Itwill now be seen by turning the Worm J the ends of the divided rim maybe drawn together, so as to securely hold it on the rim or separated sothat it may be readily with drawn laterally from the rim as willhereinafter appear. Should it become necessary to remove the tire onaccount of a puncture or for any other reason all that it is necessaryto do is first to deflate the tire, loosen the bolts G, so that theclips may be Withdrawn sufficiently far to disengage the teat on the endof the same from the recesses B when the clips maybe turned inwardly andthe curled retaining edge ring withdrawn. The worm maybe alsomanipulated as hereinbeforedescribed, so as to separate the retainingring O, which may then also be Withdrawn and the tire removed from therim and repaired if necessary. After being repaired the ,tire may bethen replaced in position by reversing the manner of procedurehereinbeiorc rclerred to.

It will be seep, from this description that my device is extremelysimple and may be readily manipulated by inexperienced people, which isan important dcsidcratum.

that l claim as my invention is i. In a pneumatic tire, the combinationwith the rim having one permanent retaining edge and the tire and theretaining ring, ot a letachable edge ring for the rim and the clipsprovided with teats extending laterally into rcccsscs in the detachablering and an inwardly extending portion fitting on the side face of thefolly and the bolts extending through the clips laterally into the follyor rim as and for the purposcspccificd.

The combination with'the rim having on which a Wrench may be applied.

one permanent edge and the tire and the reing laterally through theoutside of the side to taim'ng ring divided as shown and provided faceof the telly, Of a detachable edge ring for with lugs on each side ofthe division extend b the rim and means for holding the detachable inginto a recess in the felly, the right and I ring in position as and forthe purpose left hand screw s indie extending through 1 specified. A thecorrespondingiiy threaded holes in the 1 ARTHUR JAMES JACKSON. lugs, theWorm Wheel secured in the center of 1 Witnesses:

the spindle and the worm meshing therewith Mt BOYD,

and provided with a turning spindle extend R. SMITH.
